MALE FEMINIZATION

Myth: Soyfoods have feminizing effects on men.

Fact:

Not true! The preponderance of evidence shows that soyfoods do not feminize men or impair male fertility.

Extensive clinical research shows that even large amounts of soy do not lower testosterone levels or raise estrogen levels in men. Clinical research also shows that soy does not adversely affect sperm or semen parameters. In fact, Italian researchers suggested soy isoflavones could be a treatment for low sperm count.
